ABSTRACT:
The invention relates to a method and an electro-optical circuit arrangement for line protection in a WDM data transmission link comprising at least two selectable optical data transmission lines which can respectively transmit data via n data channels, the change-over to the respectively desired data transmission line occurring by means of optical switches between network elements on the receiver side and demultiplexers.
